[resend,0/2] Marvell A7k/A8k thermal throttling

Message

Hello,

This series works on top of Gregory's series adding both CPUfreq (already
merged) and a suitable AP806 clock driver. These two patches can fly
as-is and do not depend on Gregory's work to apply and should probably
merged independently.

With his patches, all the pieces where available to enable thermal
throttling on the AP806 embedded in Marvell Armada 7k/8k SoCs. This is
just the glue to make it actually work.

Patch 1 changes the core numbering in the thermal-zone node to be in
sync with the CPU numbering in the DT (from 0 to 3 instead of from 1
to 4). Patch 2 adds trip points and cooling maps to actually enable
the feature.

Tested with an Armada 7k DB.

Thanks,
Miquèl

Both pacthes applied on mvebu/dt64

Thanks,
